By the system and the method, high-quality whole blood can be manually collected, high-quality blood products are prepared by separation on the basis, blood quality can be positively improved, and blood transfusion safety can be positively ensured. The method includes the steps: applying the blood bag system for manually collecting the whole blood by the principle of 'proportionally adding the preservative solution in the following manner' and preparing the blood components; and establishing a whole blood collection method suitable for the system.
Description
Technical field
The present invention relates to medical domain, particularly relate to blood collecting and supplying field whole blood gather employed, as can effectively to reduce " gathering damage " equipment special and with the blood collection method of its coupling.
Background technology
The blood that the blood donor contributes must mix with contained an amount of Precerving liquid in the blood taking bag, can guarantee that blood its physical and chemical index in the storage life of stipulating of gathering meets relevant prescription with function.Yet, conventional gravity blood collection method is used in the collection of whole blood at present, the blood that is the blood donor dropwise enters in the blood bag that adds the fixed amount Precerving liquid in advance by conduit, therefore, in the whole blood collection procedure before stopping to take a blood sample, blood volume in the blood bag all can't keep correct ratio with blood Precerving liquid capacity, cause especially at the collection initial stage, the blood of gathering and the ratio of Precerving liquid are high imbalance state, make the about 30ml blood that enters the blood bag at first, be subjected to the effect of acid Precerving liquid, cause erythrocytic membrane structure and physical and chemical index to change, cause erythrocytic damage, this is erythrocytic " gathering damage ".
" gathering damage " in the blood collection procedure and storage process cause erythrocyte that a series of biochemistrys and structural change " storing damage " takes place, the two all can influence erythrocytic membrane structure, energy metabolism and physiological function, the final blood quality that influences in the storage life, back erythrocyte existence and changing function cause transfusing blood.A large amount of research datas show that the residing low pH of erythrocyte is the key factor of erythrocyte damage, and the whole blood volume in the blood bag has only the ratio correct with the maintenance of blood Precerving liquid capacity, can guarantee that just erythrocytic storage condition pH is in proper level.Domestic and international normally used whole blood Precerving liquid ACD-B, CPD and CPDA-1, the pH value of himself be respectively 5.0,5.6 and the pH value of 5.6(normal human inner blood be 7.4), they mix the final proper ratio in back and are respectively 1:4,1:7 and 1:7 with blood, can guarantee that a whole blood of gathering and storing is at the prescription that stores whole latter stage.
Although can reduce erythrocytic collection damage by the method for continuous concussion blood bag, abundant mixing in the conventional blood collection method, but in the whole blood collection procedure before stopping to take a blood sample, blood and Precerving liquid all can't keep proper proportion all the time in the blood bag, therefore, if can adopt in proportion and gather blood with adding the Precerving liquid blood collection method, to make that blood and Precerving liquid remain proper proportion in the blood bag, can reduce " gathering damage " greatly to the influence of erythrocytic membrane structure, energy metabolism and physiological function, to improving blood quality, guaranteeing that transfusion safety has positive meaning.
The invention provides a kind of blood bag system and supporting blood-sampling method with it, the principle of this system and concrete grammar utilization " in proportion with adding the Precerving liquid blood sampling " can effectively reduce the generation of " gathering damage " when gathering whole blood.
Summary of the invention
The invention provides that a kind of effective minimizing " gather damage " takes place and and carry out the blood bag system of blood constituent preparation and the blood-sampling method that foundation matches, utilize this system and method to gather high-quality whole blood and separate and prepare high-quality Blood Preparations.
Method of the present invention may further comprise the steps: the blood bag system that " in proportion with adding Precerving liquid " principle is gathered whole blood and carried out the blood constituent preparation is used in invention, sets up the whole blood acquisition method that is suitable for this system.
